Nationals GM Mike Rizzo was evasive when asked about the ballclub's pursuit of a starting pitcher like Corbin or Dallas Keuchel during an appearance on Grant & Danny Wednesday

"Well, you never have enough starting pitching," Rizzo said. "Starting pitching is the driver of, you know, winning teams. And, I think it's safe to say that we're certainly going to go down every avenue – free agency, trade-wise – to acquire starting pitching because you can never have enough of it."

Keuchel, who won the 2015 AL Cy Young with Houston, pitched to a 3.74 ERA in 204 2/3 innings in 2018.

However, the Nats are not among the favorites to sign Corbin, per MLB Network insider Jon Heyman.

Corbin is in for a visit. Phillies and Yankees are seen as favorites for PC but they are not alone in this chase. https://t.co/XhobG6Gkqb
